Facebook and Twitter have a problem. Their AI-driven recommendation engines (Facebook Groups and Twitter Trends) are fueling misinformation.That's why we're planning to publish a full-page ad in the Washington Post next week, asking Mark Zuckerberg and Jack Dorsey to shut down these recommendation engines until after the U.S. election results are certified. Will you chip in to help us run this ad?(Any additional funds we raise will support the Mozilla Foundation’s work to hold social media platforms to account, and preserve and protect the internet for all.)
